I've applied all these now - after recovering from the shock of seeing
them! :)

I think we need to have a look at/think about the no_pcm flag, partly
just in relation to the CODEC<->CODEC code as that's also figuring out
that there's no PCM but it does it just by checking that there's no DMA
driver specified.  But I'm not sure what the best thing to do is here
without seeing a machine driver or two.
